Abstract A heavy mineral analysis of sands reveals differences between Sequanian (upper Jurassic) and Albian (lower Cretaceous) formations of the Lisieux area, France. The heavy mineral suite in the horizontal well-sorted Sequanian Glos sands shows a predominance of tourmaline, zircon, rutile, and brookite. The Albian green sands differ from the Glos sands by the presence of glauconite, oblique stratification, and poor sorting at the base. A thin sandy bed intermediate between the Albian and Sequanian shows heavy mineral affinities for the Albian suite.
